Q:Acer laptop power adapter
If the computer on the trouble, it is safe on the motherboard, but not for the motherboard for another power on the line,
Q:I power adapter output current 3.25A for a 4.5A, can you use it
No problem that nominal value is that the adapter can provide the maximum operating current to your computer current is not so big
Q:How to choose the right inverter?
Inverter selection science or not for the normal operation of the frequency conversion system is essential. Many beginners on the general inverter selection method is not enough understanding, or even know the method, not sure the choice of the inverter model is positive solution, the following for everyone to solve the mystery. Inverter selection first look at the AC motor. Because the frequency conversion system generally first determine the motor, then select the inverter. In principle, it is necessary to determine the inverter model based on the actual current at which the AC motor is operating for a long time, and not on the motor nameplate. Inverter selection next depends on the load type. Frequency conversion system driven load equipment can be divided into three types: constant torque load, constant power load, fan, pump load, different load type select the inverter model is different.
Q:Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump
Hi, the inverter control is no problem. You need to select the inverter by the load characteristics of the centrifugal pump, consider: Centrifugal pump rated working current, overload capacity, parking whether there is emergency stop request. I used the inverter to control the horizontal centrifuge some time ago.
Q:Laptop power adapter in the ring is how is it?
Inductance and capacitive shock sound In fact, any inductance and capacitance work will be shocked, but some shocks are large, and some shocks are small, the frequency is not the same, and some sounds harsh, some not harsh, and some ears can not hear the range Inside. Of course, this noise also has a certain standard, in fact, listen carefully, a lot of more power consumption of electronic equipment (tens of watts or more) have a voice. So, as you said to hear the sound is very small, sharp degree is not the same. This do not control, as long as they can endure, the general sound is not great, rest assured that good use of the performance and stability of no effect.
Q:Yaskawa inverter reported base blockade what is the reason?
For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
Q:What is the application of variable frequency speed control?
Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.
Q:How to choose the inverter
Look at the motor seat size is 7.5kw it, this model of the inverter manufacturers a lot of production, and are built-in brake unit, so in the function which are the same It is important that the inverter life, stability, price comprehensive consideration Mitsubishi, Panasonic, LG, Emerson, Yaskawa, Siemens and so on
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, but is being used in the motor replacement, you need to change the frequency conversion.
Q:Three-phase asynchronous AC motor speed control method
First, variable pole alignment speed method This method is to change the way to change the stator winding red way to change the cage motor stator pole to achieve the purpose of speed, the characteristics are as follows: With a hard mechanical properties, good stability; No slip loss, high efficiency; Wiring is simple, easy to control, low prices; A level of speed, large difference, can not get smooth speed; Can be used with the regulator speed, electromagnetic slip clutch used to obtain a more efficient smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on.
